The content of Ti, Nb and Ta are colorimetrically determined by using H_2O_2, acetone-potassium sulfocyanate and pyrogallic acid respectively.

实验中采用了H_2O_2比色测定Ti，用丙酮-硫氰酸钾比色测定铌，用焦性没食子酸比色测定钽。

Xylem: Chinese P.chinensis Bge 49.15mg/g, Atlantic Ocean 46.58mg/g, UCB 55.28mg/g. 3.In certain condition, Gas-chromatograms and Mass spectrum are use to identifie phenol. Pistacia vera L .leave contain pyrocatechol 0.7640mg/g, pyrogallol 0.0580mg/g, gallic acid 1.03024mg/g, catechin 0.1040mg/g and coumaric acid by different pre-treatment methods.

采用不同方法提取阿月浑子叶片酚类物质，气相色谱-质谱法对其进行定性与定量分析，阿月浑子叶片中含有邻苯二酚0.7640mg/g；邻苯三酚0.0580mg/g；没食子酸1.3024mg/g；儿茶素0.1040mg/g，香豆酸；确定了最佳的前处理方法。

The concentration of volatile oil is higher, the reducing capability is stronger. Compared with common antioxidations, the antioxidant capacity of two species Michelia were stronger than that of PA, PG and Vc.

通过与常用抗氧化剂进行比较，发现两种含笑叶片挥发油的抗氧化能力均强于植酸PA、没食子酸丙酯PG和抗坏血酸Vc。

All PPO activity could strongly catalyze oxidative activity of pyrogallic acid, but they were very weak for the oxidative activity of chlorngenic acid.

不同杨桃品种的PPO活性有很大差异，蜜丝甜杨桃PPO对焦性没食子酸的氧化活性明显高于其他品种，而酸杨桃PPO活性极弱。

Result The fruits of 5 tested sweet carambola cultivars had PPO activity. All PPO activity could strongly catalyze oxidative activity of pyrogallic acid, but they were very weak for the oxidative activity of chlorogenic acid.

结果］5个甜杨桃品种果实中测有PPO活性，该活性均强烈催化焦性没食子酸的氧化反应，但对绿原酸的氧化活性很弱。

There was a great difference on PPO activity among different carambola cultivars. The oxidative activity towards pyrogallic acid in Misi sweet carambola was significantly higher than that in other varieties and the PPO activity in acid carambola was extremely weak.

不同杨桃品种的PPO活性有很大差异，蜜丝甜杨桃PPO对焦性没食子酸的氧化活性明显高于其他品种，而酸杨桃PPO活性极弱。

The proposed method is simple, rapid and accurate. It could be used to determine GA and EA in Sanguisorba oficinalis L. simultaneously.

本方法操作简便，结果准确可靠，适于地榆中没食子酸和鞣花酸的同时测定。

The content variations of theanine and gallic acid of solar dried green tea of Camellia sinensis var.

建立高效液相色谱分析茶氨酸和没食子酸的方法，对由云南大叶茶Camellia sinensis var。
